The rearward end of the tens transfer guiding member is shaped edge-fashion soas to resiliently lock or catch the lever 20 in either of its two end positions, by cooperation with a helical spring: E The lever 2l) is mounted on shaft 'I9 with sufcient play or freedom to permit tilting movement of lever 20 about the line connecting its catch point on the helical spring 25 with its bearing point on shaft I9, which tilting is caused by the sliding of the bent-01T portion 23 of the lever end 2| on. the inclined'l control surface 24.
